* test(heal): relative disk target and fail fast on terminal-but-short
The absolute 40 GiB heal target was calibrated to the background scanner
(auto-heal), which is now disabled for determinism; with only the explicit
heal the recovered node lands at ~36 GiB for 40 GiB survivors. Make the
success criterion relative: the outage node must reach at least 90% of the
least-used surviving node (absolute HEAL_TARGET_GB floor optional, default
0 = relative only).
Also fail fast when the heal task reaches a terminal success but the disk
target is not met (previously the monitor kept polling until timeout), and
drop the misleading 'progress absent' warning on the final (cleaned) task
response — mid-run progress is reported correctly.
Validated live: heal summary=finished, 0 failed, vm000/vm001=40GB,
vm002=40GB (target 36GB), test PASSED.
* test(heal): gate success on server verdict + data read-back, drop disk GB gate
The per-node disk-usage target (40 GiB / 90% of survivors) is not a
code-level invariant: EC distributes different shards per node, so the
final GB per node depends on the layout, not on heal correctness. Gate the
test on what the server actually verifies:
- Heal task terminal success (finished/completed) with objectsFailed == 0
(the server's per-object scan/repair verdict).
- S3 read-back verification: list the test bucket and GET a sample of
objects, requiring HTTP 200 for every read (end-to-end proof the data is
still reconstructable after repair). The GET uses a discard mode so
binary bodies are not captured (no null-byte warnings / SIGPIPE).
Per-node disk usage stays in the output as observability (with a warning if
the outage node gained no usage), not as the pass/fail gate. Removes the
heal_target_gb input and the relative-target logic.
Validated live: heal summary=finished, 0 failed, 20/20 objects read back,
vm002_used=40GB, PASS.
A fixed /tmp path (log file, final heal status, warp log) can be owned by
another user on the shared runner (e.g. a previous root run), which made the
github-runner user fail: tee could not append the test log, the final heal
status write killed step 6 with EACCES, and upload-artifact could not read
stale root-owned warp logs. The heal scenario itself had passed
(summary=finished, vm002 reached the target) before the status-save died.
- Log files fall back to a unique mktemp path when the configured path is not
writable (heal + pool scripts).
- The final heal status is written to a mktemp file (best effort).
- Workflow artifact uploads use globs for the fallback names.
* test(heal): add node-outage heal E2E script and workflow
RustFS heal test on the 3x4 cluster (3 nodes x 4 disks, same
RUSTFS_VOLUMES expression on every node): write data with warp, stop the
outage node mid-write, restart it, start cluster heal via the admin API,
and pass only when the heal task finishes with 0 failures AND the outage
node's disk usage reaches the target.
Includes the GitHub Actions workflow (smoke-testing runner, nightly deb by
default) and a README. Validated end-to-end on the test environment:
40/40/16 GiB before heal -> 40/40/40 GiB after heal, summary=finished.
The script also writes RUSTFS_HEAL_TASK_TIMEOUT_SECS (default 6h) into the
node config because the server default (5 min) is far too short for
healing tens of GiB.
* ci(pool-test): chain heal regression after the pool test
The pool-expansion workflow is now triggered by the Nightly GNU Build
(workflow_run, replacing the schedule) and runs two sequential jobs on the
shared test environment:
1. pool-expansion-test (existing) — skipped if the nightly build failed.
2. heal-test — runs after the pool test regardless of its outcome
(if: always()): a pool failure makes the run red but does not block the
heal regression. Runs the heal script (reset -> install/start 3x4 ->
write/outage -> heal -> verify -> reset).
* test(heal): address review — camelCase progress, fail-closed, workflow hygiene
- Heal progress fields are camelCase in the API (objectsScanned/objectsHealed/
objectsFailed/progressPercentage); read them with a snake_case fallback and
distinguish null (absent) progress from zero, logging null as evidence
(rustfs/backlog#2035) instead of silently coercing.
- Fail closed in step 3: the outage node must actually be inactive after stop,
the write target must be reached, and an unobserved outage or incomplete
write fails the test instead of warning.
- Step 4 waits (bounded) for the cluster to report an active pool after the
outage-node restart instead of swallowing the verification error.
- Heal start fails fast on 400/403 (deterministic request/auth problems) and
only retries transient server errors.
- Disable the background scanner (RUSTFS_HEAL_AUTO_HEAL_ENABLE=false) so the
explicit heal is the only repair mechanism and the outage is observable.
- Workflows: heal and pool share one concurrency group; workflow_run requires
an exact successful nightly conclusion; checkout is pinned to the triggering
SHA; comma-separated step args are quoted (actionlint SC2054).
* test(pool): fix warp log path and retry rebalance start
- warp writes now use a unique mktemp log file instead of a fixed
/tmp/rustfs-warp.log: the runner user could not write the stale
root-owned file, which made the background warp process die instantly
(warp never ran). The workflow uploads /tmp/rustfs-warp.*.log.
- rebalance start is retried (6x, 20s apart): nightly builds gate
rebalance activation on a live cross-pool fence fleet capability proof
that takes ~10-20s to re-establish after a pool joins. Verified live:
attempt 1 fails with 500 'pool activation requires a live fleet
capability proof', attempt 2 succeeds.
* test(pool): annotate known server-side issues in failure output
When a node fails to start, grab the rustfs journal tail and match known
server-side error signatures (e.g. the fleet capability proof cold-start
regression, rustfs/backlog#2031), printing a hint with the tracking issue.
Also annotate the rebalance-start retry exhaustion and the rc.3 decommission
metacache-listing failure with actionable guidance.
* fix(ecstore): defer rebalance activation without fleet proof

Preview tags stay as the traceability record for the validated commit, but their GitHub Releases are internal validation state and should not accumulate on the Releases page next to real deliverables.
Add a cleanup-preview-releases job that runs after publish-release succeeds for a release or prerelease tag and deletes every Release whose tag is exactly <target>-preview.<digits>. The tags themselves are kept: the job never passes --cleanup-tag. Tag matching uses jq string operations rather than a regex over the version, so dots in the version cannot widen the match, and the release listing is fetched before filtering so an API failure aborts the job instead of looking like there was nothing to clean up.
Extend the preview release workflow guard with the job condition, the delete invocation, both tag-matching filters, and an absent check for --cleanup-tag.
* refactor(site-replication): move business tests next to the service module
backlog#1840 PR5: 79 business-logic tests (plus 12 helpers, 6 of them small fixtures kept on both sides) move from the admin handler file's test module into rustfs/src/site_replication/tests.rs, next to the code they exercise: peer connection/TLS/DNS/egress validation, the peer client cache and payload wire contract, retry-queue classification/settlement/escalation/backoff, the repair state machine, bootstrap-plan construction, lifecycle expiry subsetting, bucket-target reconciliation, endpoint/identity normalization, and state serialization. The 149 tests that exercise the admin handlers, apply/reconcile paths, status/resync builders, and the four include_str! tripwires stay in rustfs/src/admin/handlers/site_replication.rs with their subjects (229 total conserved: 149 + 79 + 1).
The issue's PR5 also called for converting the source-order tripwire at the old file's line 11339 into a behavior test; both adversarial review passes re-derived all four tripwires against the shrunken file and found them non-vacuous and byte-identical in the regions they guard (the handler bodies, which did not move), so they stay as source-text assertions.
Supporting changes: the root facade's site_replication consumer gains cfg(test) re-exports (endpoint types, merge_incoming_replication_config, five lifecycle DTO types) so the relocated tests stay off the direct s3s/admin surfaces — including rewriting the one inline crate::admin BucketMetadata path a moved test carried over (review finding); tests.rs joins the logging-guardrail checked list; the embedded-secrets guard comment follows the validate_peer_connection_inner fixtures to their new file.
Verified: cargo check -p rustfs --all-targets clean; cargo nextest run -p rustfs --lib 3856/3856 passed; relocated tests run under site_replication::tests::; make pre-commit green including the s3s footprint ratchet; logging and embedded-secrets guards green.

* style(site-replication): apply rustfmt import ordering
refactor(s3-client): remove the superseded per-algorithm checksum plumbing
Deletes the write-only RequestMetadata.add_crc pipeline (assigned but never read since the port), the dead MinIO-parity Checksum constructors and CompletePart accessor, and key_capitalized (identical to key). The five hand-rolled x-amz-checksum-* response-header if-lets in the streaming and multipart paths collapse into one checksum_header_value helper, ChecksumMode's inherent to_string becomes a Display impl, and checksum.rs drops its file-wide allow blanket now that the file is lint-clean.
Refs rustfs/backlog#1844 (PR2 of 3).
Mechanical move-only extraction for backlog#1840 PR1+PR4: the site-replication state (load/parse/persist/RMW transaction), repair state machine, peer transport (client cache, DNS resolver, send_peer_* family), retry queue, and the four storage-side hooks move from rustfs/src/admin/handlers/site_replication.rs into the new infra-layer module rustfs/src/site_replication/ ({mod,state,state_lock,identity,transport,retry,repair,hooks}.rs). The admin handler file keeps route registration, all Operation impls, request/response glue, and the in-file test module, and re-exports the moved items so existing paths keep resolving. admin/site_replication_identity.rs and admin/site_replication_state.rs relocate wholesale as identity.rs/state_lock.rs.
Storage access from the moved code goes through a new site_replication consumer module in the root facade (rustfs/src/storage_api.rs), including an s3 shim so the module stays off the direct s3s surface (file count stays at the 215 baseline). The three admin runtime-source wrappers the moved code needs (outbound TLS generation incl. the test atomic, outbound TLS state, runtime port) are reproduced locally; the TLS-generation trio moves out of admin/runtime_sources.rs since site replication was its only consumer. The one non-verbatim rewrite: site_replication_peer_payload inlines encrypt_stream_io in its encrypted branch, which is provably the branch encode_compatible_admin_payload always took for the /minio/admin peer-join wire path.
app/bucket_usecase.rs now imports the three bucket hooks from crate::site_replication, deleting the three app->interface entries from the layer baseline (shrink-only). The peer-client cache test moves with the owner-local SITE_REPLICATION_PEER_CLIENT static into transport.rs (228+1 = 229 tests conserved). New module files are added to the logging-guardrail checked list; the s3_error! line baseline tightens 1620 -> 1619; global-state/config-consumer inventories and ARCHITECTURE.md pointers updated.
Verified: cargo check -p rustfs --all-targets clean; cargo clippy --workspace --all-targets clean; cargo nextest run -p rustfs --lib 3852/3852 passed; make pre-commit green; scripts/check_layer_dependencies.sh green with baseline-only deletions; line-multiset conservation audit over the moved code accounts for every non-verbatim line (visibility bumps, import rewrites, fmt reflow).

refactor(ecstore): retire the set_disk lint blankets by making the prelude explicit
backlog#1823 step 1 / backlog#2029 road 2. Removes the last two module-level lint blankets in ecstore: set_disk/mod.rs #![allow(unused_imports)] and #![allow(unused_variables)], restoring both lints for the whole 40K-line subtree, and deletes the register line for the unused_variables blanket in the same diff (the guard from #6155 is a bidirectional exact match).
The unused_imports blanket existed because 14 submodules consumed mod.rs as a glob prelude (use super::* / use super::super::*), and rustc does not track consumption through glob re-exports. Each glob is now an explicit use super::{...} list, keeping mod.rs as the single import hub while making every import lint-checkable. Names consumed only by test or test-util units carry #[cfg(test)] / #[cfg(all(test, feature = "test-util"))] / #[cfg(any(test, feature = "test-util"))] gates matching their consumers; storage-api traits are routed through the storage_api_contracts facade per the architecture guard.
The sweep then deleted the genuinely dead imports the blanket was hiding (chrono::Utc, glob::Pattern, futures::task::AtomicWaker, rustfs_lock LocalLock, AsyncBatchProcessor, rand::Rng, std::future::Future among others in mod.rs, plus stale scoped imports and one empty test module shell across the subtree). One unused_variables finding surfaced: flush_read_version_coalescer_pending's lane_key is read only by the #[cfg(test)] counter block, handled with the cfg(not(test)) let _ pattern established in #6158.
Verification: cargo check zero warnings versus the 9cf276ed2 baseline on five lanes (default lib / --tests / rio-v2 --tests / test-util --tests / test-util,rio-v2 --tests; the --tests lane keeps the same three pre-existing core/pools.rs and store/object.rs dead-code warnings main already has); clippy --lib --tests -D warnings clean with test-util,rio-v2; cargo nextest run 4567 passed; make pre-commit exit 0.
* refactor(ecstore): drop the client shim, import rustfs-s3-client directly
Completes the migration window opened by the rustfs-s3-client extraction (rustfs/backlog#1842 PR3): every consumer now imports the client crate directly and the crate::client shim is deleted.
- All in-crate crate::client:: paths (tier warm backends, tier core, lifecycle tier_sweeper, replication storage boundary, set_disk) now import rustfs_s3_client::* directly; crates/ecstore/src/client/mod.rs and the lib.rs mod client declaration are gone.
- The two server-side modules historically misfiled under client/ move to their real homes: object_api_utils.rs to crates/ecstore/src/object_api/ (it builds engine-side object readers/writers), and object_handlers_common.rs to crates/ecstore/src/bucket/lifecycle/ (it is the lifecycle noncurrent-version cleanup helper). The latter now routes its replication calls through the lifecycle replication_sink boundary (schedule_delete wrapper and the sink's ReplicationObjectBridge re-export), as the lifecycle guard requires.
- The ecstore public facade drops api::client: object_api_utils is exposed as api::object_api_utils, and the rustfs crate takes admin_handler_utils (AdminError) from rustfs-s3-client directly (new dependency).
- Guard updates: the migration guard no longer pins mod client in ecstore's lib.rs or the admin_handler_utils facade module (it pins the new api::object_api_utils facade instead), and the module-lint register follows object_api_utils.rs to its new path.
Verification: cargo check -p rustfs-ecstore --all-targets and -p rustfs; cargo fmt --all; tier/transition/lifecycle-focused nextest (626 passed) and the decommission/rebalance/heal families in a filtered run (603 passed; the full-suite parallel run only fails on this machine's known decommission/rebalance baseline flakes, which pass in filtered reruns and fail identically on pristine origin/main); layer/migration/s3s/logging/error-format/doc-path guard scripts all pass.
* docs(architecture): record the S3 client extraction and reword invariant 4 (#6669)
Closes the documentation step of rustfs/backlog#1842. ARCHITECTURE.md invariant 4 now states the serving-vs-consuming distinction the adversarial ruling asked for: ecstore must not serve HTTP/S3 wire types, while consuming remote S3 endpoints is a legitimate engine capability that lives in the extracted rustfs-s3-client crate. The violation note is updated from the pre-extraction snapshot (58 files, embedded client) to the current ratcheted state (shrink-only S3S_ECSTORE_FILES_BASELINE in scripts/check_s3s_footprint.sh, object_lock converted first), and the crate map gains s3-client. ecstore-module-split-plan.md gets the client-directory entry the plan was missing: a Current Shape row and a completed-extraction section describing the pure-move + shim + direct-import sequence and the re-homing of the two misfiled server-side modules.
* refactor(rustfs): carve app/object out of object_usecase.rs — shared, extract, test_support children (backlog#1841 step 1)
Mechanical move-only split of rustfs/src/app/object_usecase.rs (19.7K lines). The file body moves to rustfs/src/app/object/mod.rs, and the first self-contained slices move into children: shared.rs (cross-cutting helpers: quota admission, response checksum injection, object-lock write validation, table-catalog mutation guard, deadlock request guard, proxy passthrough utilities), extract.rs (snowball auto-extract path incl. tar/pax helpers and execute_put_object_extract), and cfg(test) test_support.rs for cross-module test scaffolding. object_usecase.rs stays as a thin pub use facade so every existing crate::app::object_usecase:: path keeps working.
No behavior change: items move verbatim; the only source edits are visibility widenings required by the new module boundaries (private -> pub(super); pub(super) -> pub(crate) for the three helpers multipart_usecase and the app gating tests import). Guard scripts that pinned rustfs/src/app/object_usecase.rs now scan the rustfs/src/app/object tree, and the table_catalog source-text guard test concatenates the split files.
* refactor(rustfs): move the GetObject read path into app/object/get.rs (backlog#1841 step 2)
Move-only continuation of the object_usecase split: cold-fill orchestration, disk-permit admission, streaming readers and resume control, stream-buffer tuning, execute_get_object / execute_get_object_attributes, the GET replication proxy helpers, and their unit tests move from app/object/mod.rs into app/object/get.rs. Items keep their original text; cross-module call sites rely on the visibility widenings introduced in step 1.
* refactor(rustfs): move the PutObject and CopyObject paths into app/object (backlog#1841 step 3)
Move-only continuation: put.rs takes the PUT body admission and timeout readers, zero-copy and eager-commit machinery, execute_put_object, and the PUT unit tests; copy.rs takes the copy namespace/lifecycle lock helpers and execute_copy_object with its tests. Two source edits beyond visibility widenings: PutObjectChecksums fields become pub(super) (read by shared::apply_trailing_checksums across the new module boundary) and one relative super::storage_api call in the copy path becomes crate::app::storage_api since super now resolves to app::object. The table_catalog source-text guard concatenates the new files.
* refactor(rustfs): finish the object_usecase split — delete, head, restore modules (backlog#1841 step 4)
Move-only completion: delete.rs takes the delete helpers, cfg(test) delete hooks, and execute_delete_object/execute_delete_objects; head.rs takes execute_head_object with the HEAD replication proxy helpers; restore.rs takes execute_restore_object. app/object/mod.rs is now just the shared import prelude, module wiring, and the DefaultObjectUsecase struct with its constructors, accessors, and the execute_select_object_content delegation; the emptied tests module is gone. The delete re-export glob is cfg(test)-gated because its only cross-module consumers are the delete test hooks.
The table_catalog source-text guard now isolates the delete entrypoints from app/object/delete.rs, and doc/comment references that pointed at rustfs/src/app/object_usecase.rs internals now point at the per-operation modules.
The object_lock module evaluated WORM state through s3s wire DTOs (ObjectLockRetention, ObjectLockLegalHold, DefaultRetention, Date) and s3s header constants, keeping the storage engine coupled to the serving protocol (rustfs/backlog#1842, ARCHITECTURE.md invariant 4). This PR gives the module its own storage-level vocabulary and pushes the DTO conversions to the boundaries that already speak s3s.
New crates/ecstore/src/bucket/object_lock/types.rs defines RetentionMode, LegalHoldStatus, ObjectRetention, ObjectLegalHold, and DefaultRetention with no s3s dependency. objectlock.rs parses persisted metadata into these types using the rustfs-utils lowercase header constants (the same literal keys as before, pinned by the existing g-key-002 test). objectlock_sys.rs evaluates retention/legal-hold/default-retention from them; the fail-closed error messages and decision logic are unchanged line for line where possible.
Boundary conversions:
- bucket/metadata_sys.rs gains default_retention_from_object_lock_config, converting the persisted s3s configuration into the storage-level DefaultRetention; a rule without a usable GOVERNANCE/COMPLIANCE mode converts to None exactly like the evaluation code always ignored it, and days/years pass through so an invalid period still fails closed at evaluation time.
- check_object_lock_for_deletion_with_config becomes check_object_lock_for_deletion_with_default_retention (it only ever read the default retention); the lifecycle object_lock_boundary keeps the old s3s-typed signature and converts.
- The ObjectLockApi / ObjectLockStatusExt trait impls for the s3s DTOs move next to the persisted configuration owner in bucket/metadata.rs; the traits stay in object_lock/mod.rs.
- check_retention_for_modification now takes Option<RetentionMode>. The serving-layer wrappers (rustfs storage_api, set_disk options path) convert the request string with the new RetentionMode::parse_exact, which accepts only the canonical spelling — preserving the historical literal comparison where a non-canonical requested mode reads as a mode change and stays blocked.
- rustfs app-layer wrappers return the storage types; the replication-overwrite gate in object_usecase.rs uses the typed API (legal_hold.is_on(), RetentionMode::Compliance).
Ratchet: the ecstore-scoped s3s counter drops 42 -> 39 and the repo-wide file counter 211 -> 208 in scripts/check_s3s_footprint.sh.
Verification: cargo check -p rustfs-ecstore --all-targets and -p rustfs (lib+bins); cargo clippy -p rustfs-ecstore --all-targets and -p rustfs --lib --bins (clean); cargo nextest run -p rustfs-ecstore --no-fail-fast (4534/4542; the 8 failures are the same store::rebalance / store::heal machine-baseline set that fails identically on pristine origin/main, plus one fencing flake that passes in isolation); all object_lock/retention/legal-hold tests pass; guard scripts (layer deps, migration rules, s3s footprint, logging, error-format ratchet, doc paths) pass.
* ci(nightly): persist the nightly deb on Cloudflare R2
Upload the deb to artifacts/rustfs/packages/nightly/ (dated name plus a
rustfs-nightly-latest.deb alias) through the same R2 channel package.yml
uses, so the nightly package can be downloaded later with a stable URL.
The step is skipped when the R2 secrets are not configured, keeping the
artifact-only mode intact.
* test: add pool expansion / decommission E2E script and workflow
Add the admin-API based pool expansion, rebalance and decommission test
script (scripts/test/rustfs_pool_expand.sh) plus a workflow_dispatch /
nightly workflow that runs it on a self-hosted runner against real nodes.
The workflow accepts a release tag or a direct .deb URL (e.g. nightly/R2
package) via the package_url input.
* ci(pool-test): run the pool expansion test on the smoke-testing runner
The storage engine embedded a ~8.4K-line hand-written S3 HTTP client under crates/ecstore/src/client (rustfs/backlog#1842). That client is a legitimate engine capability — it consumes remote S3-compatible endpoints for ILM tier warm backends and transition targets — but it was misfiled inside the engine, dragging s3s/hyper wire types into ecstore and blocking ARCHITECTURE.md invariant 4.
This PR is the pure-move step: 21 modules move verbatim to the new crates/s3-client crate (rustfs-s3-client), and crates/ecstore/src/client/mod.rs becomes a re-export shim so every in-crate crate::client:: path keeps working. The two server-side modules that were historically misfiled under client/ — object_api_utils.rs and object_handlers_common.rs — stay in ecstore.
Three reverse dependencies from the client into engine internals are severed so the move can be pure:
- transition_api::ReaderImpl::ObjectBody held ecstore's GetObjectReader; the client only ever reads the body, so the variant now holds an ObjectReader newtype over Box<dyn AsyncRead + Send + Sync + Unpin> with the same read_all() surface. The single production construction site (set_disk transition upload) and the two engine-side consumers were adjusted.
- api_list/api_remove used ecstore's storage_api_contracts / object_api types; api_list now imports BucketInfo from rustfs-storage-api directly, and api_remove uses the client's own transition_api::ObjectInfo (only .name/.version_id were read; the error-path bucket name is now threaded as a parameter instead of read from the deleted objects).
- the api_put_object_streaming regression tests built a GetObjectReader by hand; they now wrap the duplex stream in ObjectReader::new.
Guard updates: the s3s footprint ratchet gains an ecstore-scoped counter (42 files, shrink-only, per rustfs/backlog#1842), the ecstore module-lint-blanket register follows the moved files into crates/s3-client so the blanket ratchet keeps covering them, the logging guardrail path pin follows transition_api.rs, and the ::other(format!) baseline is regenerated (moved call sites left ecstore).
Verification: cargo check -p rustfs-s3-client -p rustfs-ecstore; cargo nextest run -p rustfs-s3-client (43 passed) and -p rustfs-ecstore (4515/4523; the 8 failures reproduce identically on pristine origin/main on the same machine); cargo clippy --all-targets; scripts/check_layer_dependencies.sh, check_architecture_migration_rules.sh, check_s3s_footprint.sh, check_logging_guardrails.sh, check_error_other_format_ratchet.sh, check_doc_paths.sh, check_ci_paths_sync.sh all pass.
* feat(ecstore): type internode client-acquisition failures for stable quorum buckets
Backlog#1845 step 3, first typed family. The largest other(format!) message family in ecstore was 'can not get client, err: {detail}' (~50 production sites): every internode RPC that fails to acquire a client wrapped the dial/auth error with per-peer detail into DiskError::other / StorageError::other, whose Io equality compares the rendered message. N disks failing for this same cause therefore counted as N distinct errors in reduce_errs, starving quorum aggregation, and remote_disk call sites double-wrapped the message on top of get_client's own wrap.
Introduce DiskError::RemoteClientUnavailable(String) (wire code 0x2B) and its StorageError twin (StorageErrorCode 0x54): equality and hashing use the wire code alone, so same-cause failures land in one quorum bucket regardless of per-peer detail, while Display keeps the detail so substring classifiers (network needles, heal recoverability) keep reading it unchanged. Wire encoding carries the rendered detail in error_info and decode restores the typed variant; old peers fall back to the legacy string form gracefully.
Call sites: remote_disk get_client/get_bulk_client/offline-bypass/recovery-probe now construct the typed variant and the ~60 redundant double-wrap map_errs are gone; peer_rest_client's three client getters and offline gates, peer_s3_client, and admin_server_info follow. The tier-config-reload connection classifier's anchored 'can not get client' substring check becomes a typed match on the variant (the string form is retired and now classifies as Terminal, pinned by test).

refactor(protos): move internode compat manifest send-site assertions into owning crates
Promotes the rolling-upgrade dual-write manifest from a test-only constant in rustfs-protos into the public rustfs_protos::compat_manifest module, moves the JSON-encoder send-site assertions into the crates that own the asserted sources (ecstore remote_disk.rs for requests, the rustfs binary node_service/disk.rs for responses), and splits the scanner Phase-0 overlap inventory so its heal- and ecstore-owned halves live in those crates. Adds a cross-crate include_str!/include! guard with fixture self-tests to scripts/check_layer_dependencies.sh so a library crate can never again read another crate's Rust source at compile time, and records the rule in docs/architecture/crate-boundaries.md.
Part of rustfs/backlog#1884.
Backlog#1845 step 2. reduce_errs buckets per-disk errors by equality, and Io equality compares the rendered message, so an other(format!(..)) error embedding per-disk detail makes N same-cause failures count as N distinct errors during quorum aggregation. The census that opened the issue counted 1,609 such sites; the production count in crates/ecstore/src is 657 today and was still growing.
Freeze it: scripts/check_error_other_format_ratchet.sh counts ::other(format! sites per file (trailing #[cfg(test)] modules excluded) against a shrink-only per-file baseline, failing on any growth and on stale entries after a shrink, following the layer-dependency-baseline model. Wired into make pre-commit / pre-pr / dev-check and the CI Quick Checks job.

test(obs): replace source-text logging tests with logging guardrail script coverage
The seven fs::read_to_string source-text tests in crates/obs/src/logging.rs asserted retired logging patterns and required structured-logging fields across 13 files in other crates, four of them reverse reads into the rustfs binary crate. Their patterns are now enforced by scripts/check_logging_guardrails.sh, which runs in pre-commit and CI, covers the same files through checked_files plus require_patterns, and does not silently lapse when a governed file moves.
